Embodiment 1

[0024] A high-gloss anode process for aluminum products, comprising the following steps:

[0025] Step 1): Grinding the surface of the aluminum product with a 600# abrasive belt;

[0026] Step 2): Use a 600# nylon wheel to polish the surface of the aluminum product;

[0027] Step 3): Use a sackcloth wheel with green wax for initial polishing;

[0028] Step 4): Use a cloth wheel with white wax for fine polishing;

[0029] Step 5): anode reaction;

[0030] The anode reaction specifically includes the following steps: a. wax removal; b. polishing and neutralization; c. oxidation; d. dyeing;

[0031] a Wax removal: add wax removal water into the wax removal tank, turn on the air to stir, heat up to 55°C and fully dissolve, fix the aluminum product on the hanger, immerse the hanger with the aluminum product in the wax remover tank for 1 minute, and then take it out Enter the washing tank for washing;

[0032] B chemical throwing, neutralization:

[0033] Chemical polishing: a...

Embodiment 2

[0042] Aluminum products were processed according to the same process as in Example 1, except that step 5): anodic reaction:

[0043] a Dewaxing: Add dewaxing water into the dewaxing tank, turn on the air and stir, heat up to 50°C and fully dissolve, then fix the aluminum product on the hanger, immerse the hanger with the aluminum product in the dewaxer tank for 2 minutes, and then take it out Enter the washing tank for washing;

[0044] B chemical throwing, neutralization:

[0045] Chemical polishing: add chemical polishing agent into the chemical polishing tank, turn on the air stirring, and heat up to 105°C; immerse the aluminum product in the chemical polishing tank to react for 60 seconds, then take it out and wash it in the washing tank; the chemical polishing agent is 85 % phosphoric acid, and 160 ml / L of 98% sulfuric acid mixed solution;

[0046] Neutralization: Then add a nitric acid solution with a nitric acid concentration of 260g / L into the neutralization tank; i...

Embodiment 3

[0051] Aluminum products were processed according to the same process as in Example 1, except that step 5): anodic reaction:

[0052] a Dewaxing: Add dewaxing water into the dewaxing tank, turn on the air to stir, heat up to 60°C and fully dissolve, fix the aluminum product to the hanger, immerse the hanger with the aluminum product in the dewax tank for 1.5min, then Take it out and wash it in the washing tank;

[0053] B chemical throwing, neutralization:

[0054] Chemical polishing: add chemical polishing agent into the chemical polishing tank, turn on the air stirring, and raise the temperature to 120°C; immerse the aluminum product in the chemical polishing tank to react for 20 seconds, then take it out and wash it in the washing tank; the chemical polishing agent is 85 % phosphoric acid, and 140 ml / L of 98% sulfuric acid mixed solution;

[0055] Neutralization: Then add a nitric acid solution with a nitric acid concentration of 300g / L into the neutralization tank; immer...
